Fig. 10 shows the series of lugs, or projections on a post.

Referring to the drawings in detai1:-

I and 2 designate the two posts which are preferably located on the to protect from being injured, 7 motor vehicle, or any other means. These posts, as shown, are formed with a broadened, or flaredout base portion 5. 6 designates a concrete raised portion above the street level which portion is a part of the securing means of the posts, indicated by the metal, angular-shaped member 8, (see Fig.7), having the arm members 9 and it],

in the apex of which the rod 4 l is welded, as shown. This rod is. formed l2, to receive an eye, or link sion rod l3, which is located adjusting the tension of a coiled spring l3". details of this tension means are also shown. described and claimed in my co-pending application. I 4 indicates a wire reinforcing means in the block of concrete 6.

The tree, or hydrant-protecting means comprises the metal band, or bar members l5, three of which are shown. These bands are secured, at their free ends, to the posts I and 2, by means of the post fittings I6, shown in Fig. 1. These members are formed with a recess H, which is designed to freely pass over the projections l8 and I8 on the posts. The post fitting members I6 are then turned 90 out of register with the openings [1. Lugs I 9, on the posts I and 2, are located below the post fittings I6 for supporting these fittings.

It should be stated and openings I! are of that the lugs Hand [9 different sizes, increasing the lowermost fitting l 6, and the one immediately above, or the middle fitting, may be installed on the post, and supported thereon, in their proper positions, (see Fig. 10).

The post fittings iii are securely supported on the posts by cooperation with the integral lugs any device attached to the fittings. The lowermost fitting l6 hasa slot wide enough to pass the lugs IS, the upper of the lugs l9, and the lug I8, but too narrow to pass the lower lug l9, and the middle fitting I6 is provided with a slot wide enough to pass the lugs I 8 only. The upper fitting I6 is provided with no slot, and rests directly on the upper lug I8. Because of this construction, the lowermost fitting l6 will slip over all the lugs except the bottom lug l9, upon which it will rest; the middle fitting 3 will slip over the lugs l8 and rest on the upper lug l9, and the top fitting IE will slip over the top of the post and rest on the upper lug l8 and under the cap 30.

The bands l5 are secured to these fittings by means of the bolts 20.

In Fig. 2, the bands l5 are duplicated on the opposite side of the tree 3, and the fittings l6 are formed with the double arm portions l6.

Referring to Fig. 3, the bands l5 are connected to the semi-circular clamps 2| and 22 having the hinge joint 23. 24 indicates a securing member for normally retaining the clamps 2| and 22 in place onthe post 2. This member is formed with a head 25, which, when turned will lay across the slot 26, and, when parallel thereto, will readily pass through this slot, permitting the bands I5 to be swung into the dotted line position I5". The same tool that is used to engage the screw bolt 21 of the hydrant will fit the member for turning the same.

Referring to the construction shown in Fig. 8, the post i is formed with the plate 28 through which the tension rod l3 passes. The upper end of this rod is threaded to receive the nut 29. The nut is for varying the tension of the coiled spring l3". for the purpose of maintaining the post in a vertical position and to limit the movement of the same into an inclined position, in either direction, as shown in the dotted line positions I and I". In Fig. 9, when the post is tilted, the.

coils of the spring l3 are closed. By making the spring 13" of large gage wire, theresistance to tilting is increased, and, will also offer resistance to its sliding on the concrete 6.

A suitable cap member 30 is provided for the tubular post I, as shown, and is held in place with the pin 3|.

It is to be understood that I do not limit myself to the use of bands, as a tree or hydrant protective means that are secured to the posts I and 2; but I may, if desired, employ wire cables, chains, or fabricated sheet metal in their place. This construction may be used around large trees by using several posts, instead of two, as shown.

Also, any suitable means may be employed for attaching these protective means.

What I claim is:--

1. A safety fence post comprising a fiat base plate, means for anchoring said plate, a tubular post member slidably supported on said plate, a hook member rigidly secured on said anchoring means, resilient connecting means including a link member between said hook member and said post member.

2. A safety fence post comprising a flat base plate, means for anchoring the said plate, a tubular post member slidably supported on said plate, a hook member rigidly secured on said plate, resilient connecting means between said hook and said post, said resilient connecting means comprising an internal shoulder in said post, a compression spring seated on said shoulder, a bolt passing through said spring, a link member pivotally connecting said bolt to said hook, a washer engaging the top of said spring, and a nut threadably secured on said bolt above said washer, said nut and washer providing means for adjusting the compression of said spring.

3. A safety fence post comprising a base, a W bular open-ended post slidably supported on said base, said post being formed with an integral internal transverse partition formed with an axial opening, a compression spring within said post and having an end supported on said partition, a rod passing through said spring and said opening, means on the upper end of said rod for adjusting the compression on said spring, the lower end of said rod being formed with an eye, a hook rigidly secured in said base, a link connecting said hook and said eye, and an imperforate cap removably secured over the upper end of said post, whereby said post when subjected to impact will first move laterally to the limit of said link and then tip.
